Front

What causes a very bright star to appear dimmer?

Back

It can appear dimmer because it is further away.

Front

What is the brightness of a star as seen from Earth called?

Back

Apparent brightness.

Front

Why does the moon look larger than the stars?

Front

What is absolute magnitude?

Back

The intrinsic brightness of a star, measured at a standard distance of 10 parsecs.

Front

What is apparent magnitude?

Back

The brightness of a star as seen from Earth, which can be affected by distance and interstellar material.

Front

What is the relationship between temperature and color in stars?

Back

Hotter stars emit blue light, while cooler stars emit red light.

Front

What is parallax in astronomy?

Back

The apparent shift in position of a nearby star against the background of distant stars as observed from different positions of Earth.

Front

How does distance affect the apparent brightness of a star?

Back

As the distance increases, the apparent brightness decreases.
